Hello Jamenson,
You cannot use cat (Unix utility) to concatenate .VOB files.
You cannot use the FFmpeg concat filter to concatenate ALL of the .VOB
files, and you tried to do all of them. (This might work in extremely
rare cases, but I doubt it ever does with a realistic DVD.)
The answer from Micael Silva hints at the problem with concatenating
everything, but let me go more in depth:
The video_ts.vob file is not really movie content, it is metadata.
The vts_xx_y.vob files may or may not be movie content, but they VERY
often have different stream(s) in them. VTS stands for "Video Title
Set". The xx, the 2-digit number, is the title. The feature film is one
title (almost always). On your DVD, the feature film is vts_01_y.vob, so
it is "title 01". The feature film is usually title 01 or title N, where
N is the biggest number used on the disc.
Within a given title, such as vts_01_y.vob (the feature film on your
DVD), there are up to 10 VOB files, with y from 0 to 9. The file
vts_01_0.vob, with y == 0, may or may not be safe to concatenate with
the rest of this title, it may or may not have the same streams. Yours
is 320 megabytes, so it might be safe. If it was super small, then it
would likely just be a menu.
The VOB files vts_01_y.vob for y from 0 or 1 to as high as it goes (y ==
4, for your DVD) can be safely concatenated, and the result will be one
title. In your DVD, this one title will be the feature film.
vts_02_y.vob, vts_03_y.vob, and the other titles are likely special
features, and they cannot be concatenated safely. They likely have
different streams, and possibly even different resolution, frame rates,
or all kinds of differences that will not fit inside a single MKV file.
SUMMARY: You only want to concatenate VOB files from the same title. The
other titles (2 through 5, on your example DVD) are special features or
something, they are not the movie itself. You also want to avoid the
video_ts.vob file and you may need to avoid the vts_xx_0.vob file.
More notes:
1. I don't think you can use -codec:v copy -crf 20. It doesn't seem like
it should be allowed. -codec:v copy means "don't touch the bytes", but
-crf 20 implies you want to use libx264 and you want that quality of output.
2. I don't think you can use -codec:a copy -qscale:a 2 for a similar
reason, 'copy' means "don't touch the bytes".
3. You can maybe theoretically use -codec:s copy with the output being a
.MKV file, but DVD subtitles are very user-unfriendly in MKV containers.
If at all possible, I suggest using WebVTT or SubRip (filename.srt)
format subtitles in your MKV file. The subtitles on the DVD are not
actually text, they are images. They need to be processed by OCR and
then converted into a text-based subtitle format such as WebVTT or
SubRip (filename.srt).
4. The MP4 container file can't handle several of those things: It can't
handle subtitles in that format, it can't handle audio in that format
(edit: actually, it looks like VLC will play an MP4 file with AC-3
audio, but iTunes will not), and it may not be able to handle two full
5.1-channel audio streams, I forget. In fact, MP4 files almost don't
handle subtitles at all, they support one format that is weird, if I
recall correctly.
5. Depending on your goals, I'm not sure if FFmpeg is what you want to
use to convert this DVD into a more user-friendly MKV or MP4 file. I
might suggest HandBrake with the GUI interface, I suspect it may do what
you want. FFmpeg is utterly impressive, it can do a huge array of
things, but the HandBrake GUI application will find the names for the
"titles" on the DVD (the feature film, the making of featurette, the
deleted scenes), it will ignore vts_01_0.vob if it needs to but keep it
if it should, stuff like that. You can select "MP4" from the drop-down
menu and then it will tell you "I can't put AC-3 audio in an MP4
container, please use a MKV container or I might I suggest transcoding
to AAC". It's not as awesome as FFmpeg, but given the VOB files you have
and the MKV or MP4 you want to make, HandBrake can probably do it much
less painfully.
Good luck,
Zak
